Authoritarian dominant parties are said to ensure elite loyalty by providing elites with regularized opportunities for career advancement. This article uses data on the distribution of leadership posts in Russia’s regional legislatures (1999–2010) to conduct the first systematic test of this proposition. Loyalty to the nascent hegemonic party, United Russia, is shown to be important in determining a legislator’s chances of being promoted to a leadership position. These findings generate insight into how authoritarian institutions help maintain regime stability and provide a clearer picture of how Russia’s ruling party works.
